Popis:	Zooglan-115 shows Newtonian flow at a concentration of 0.2% or less, Bingham flow between 0.2 and 0.4%, and mixed flow greater than 0.4%. It was stable in the pH range 3.0–10.0. Zooglan-115 is compatible with most gum systems such as guar, locust bean, arabic, karaya, xanthan, and tragacanth, but shows an antagonistic effect with cellulose backbone glycans, microcrystalline cellulose, and CMC. A 0.1% solution at 22°C reduced the surface tension of water from 72 dynes/cm to 63 dynes/cm, and also lowered the interfacial tension with winterized soybean oil from 19 dynes/cm to 12 dynes/cm. The combined functional properties of viscoelasticity (and therefore possessing a yield value), surface-activtity, acid stability, and salt compatability enable Zooglan-115 to be a good stabilizer/emulsifier when used in oil-in-water emulsion systems.
